1,302,419, Specification of Letters Patent. Patented Apr, 29, 1919,

- Application filed April 18, 1917. Serial No. 162,863.

To all whom it may concern:

Be it known that I, CLARENCE A. NOTMAN, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new anduseful Improvements in Stoves, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to stoves, and has special reference to a single burner gas or oil burning stove that has an oven, broiler, cooking top or top plate heated by a single burner.

My invention aims t provide a stove of the above type that may be characterized by being devoid of castings, with the exception of a burner, as the remaining parts of the stove are stamped and pressed from sheet metal, finished to avoid corrosion, present a neat appearance and permit of the parts of the stove being easily and quickly assembled. The design and construction of the various parts insures rigidity with a minimum weight when the parts are assembled and buckling or distortion of those parts subj ected to an intense heat is prevented by the conformation of the metal and particularly novel heat disseminating ribs in connection With the cooking top or grid of the stove.

My invention is further characterized by a stove that permits of extensive cooking with a minimum expenditure of fuel and provision has been made for increasing or decreasing the overall area of the cooking top so that the stove may be placed in a suitable space. Furthermore, it is through the medium of detachable legs that the stove may be placed upon the table or other suitable support and these and other features make the stove very convenient for small compartments or kitchenettes.

My invention still further aims to provide a stove wherein the parts are constructed with a view of reducing the cost of manufacture and at the same time retain those features by which safety, durability and ease of cooking are secured. \Vith such ends in view, my invention resides in the novel construction, combination and arrangement of parts to be hereinafter specifically described and then claimed.

Reference will now be had to the drawings, wherein- Figure 1 is a vertical cross sectional view of a stove with one of the legs thereof broken away;

Fig. 2is a plan, on a small scale, of a portion of the stove; 1

Fig. 3 is a perspective view of a portion of the stove showing a clamping socket;

Fig. 4 is a perspective view of a portion of a corner piece;

Fig. 5 is a perspective view of portions of a corner piece and a leg;

Fig. 6 is a perspective view of a portion of a shelf;

Fig. 7 is a detail view showing the posi tioning means of the burner;

Fig. 8 is a longitudinal sectional view of a portion of the stove;

Fig. 9 is a top plan of the stove;

Fig. 10 is a horizontal sectional view of a portion of the stove, and

Fig. 11 is a detail sectional view of a portion of a detachable shelf.

In describing my invention by aid of the views above referred to, I desire to point out that the same are merely illustrative of the stove as now constructed, and I do not care to confine myself to the precise construe tion and arrangement of parts shown. The following description is therefore to be broadly construed as including such substitute constructions and arrangement of parts which are the bvious equivalent of those to be hereinafter referred to.

In the drawing, 1 denotes an oven shell rectangular in plan and having the front wall thereof cut away to provide a doorway 2, while opposed side walls thereof are provided with inset ortions or ledges 3 adapted for supporting a shelf or grid (not shown at denotes a bottom plate set in the oven shell and provided with depending flanges 5.

6 denotes corner pieces, preferably in the form of angle bars that are placed at the vertical corners of the oven shell and these corner pieces have the upper ends thereof terminating in tongues 7 protruding above the walls of the oven shell so as to form shoulders 8 in the same plane as the upper edges of the oven wall. The lower ends of the corner pieces 6 are inbent to provide shoulders 9 and depending auxiliary legs 10. The lower edges of the oven shell 1 are adapted to rest upon the shoulders 9 and each corner piece has an instruck lug 11 to support the flange 5 of the inset bottom plate 4, and when the corner pieces, oven shell 1 and bottom plate 4 are all assembled it is practically impossible for the bottom plate 4 to become accidentally displaced.

11 denotes legs that permit of the .oven or stove proper being supported in an elevated position and these main legs have the upper ends thereof formed with inturned flanges 12 cooperating with the angular bodies of the legs in providing sockets to receive the auxiliary legs 10 while the upper ends of the legs 11 abut the corner pieces 6. The corner pieces 6 are practically a continuation of the legs 11 and when said legs are not used, the-auxiliary legs 10 will support the oven or stove proper on a table, shelf or other support.

13 denotes a cooking top or hot plate having a central circular opening surrounded by a gutter 14, and seated in this gutter is a grid or center plate 15 provided with concentric corrugations 16 which add rigidity to the grid and assist in the radiation of heat. The cooking top 13 is rectangular in plan and has depending side flanges 17 terminating in lateral portions 18. Flanged over the lateral portions 18 of the flanges 17 is an intermediate plate 19 having a central opening 20 directly beneath the grid 15. The intermediate plate 19 is provided with angle openings 21 to receive the tongues 7 at the upper ends of the corner pieces 6, so that the intermediate plate 19 may rest upon the shoulders of the corner pieces and support the cooking top.

22 denotes corrugations or ribs of the top 13 and these corrugations or ribs are substantially radially disposed so as to prevent undue distortion of the top 13 and assist in radiating heat.

23 denotes slots in the flanges 17 of the top 13 and these slots permit of outstruck hook portions 24 of detachable shelves 25 being placed against the flanges 17 and supported in the same horizontal plane as the top 13. The hook portions 24 of the shelves 25 engage under the upper walls of the slots 23 with the shelves resting against the flanges 17 and on the flanged portion or edges of the intermediate plate 19, as best shown in Fig. 10. It is preferable to make the shelves 25 of a single piece of material, at the sides of the stoves, but at the rear portion thereof it is preferable to make the shelf in two sections, so that one may be dispensed with if I outpressed barrels that extend through the doorway 2 so that the door 27 may have its barrel pivotally or hingedly held as has been indicated at 28. The door 27 has a glass panel 30, a knob 29, and is adapted to be swung into engagement with a transverse name plate or brace 50 connecting sides of the doorway 2, at the top thereof. A gravity latch or lock 51, carried by the brace 50 retains the oven door closed.

31 denotes a burner positionedbelow the opening 20 of the intermediate plate 8, and this burner hasa gas or oil inlet pipe 32 thereof extending through an opening in the side wall of the oven shell 1 and correctly positioned by lugs 33 on the pipe 32. An opening 52 in the opposite oven wall permits of the pipe 32 extending into the oven from either side. At the outer end of the inlet pipe 32 is an air mixer 34, a valve 35 and the usual gas or oil supply pipe 36.

From the foregoing, it will be observed that the single burner 31 serves to heat the oven as well as the cooking top of the stove and that this cooking top may be made of sufficient area so that a plurality of utensils can be placed thereon for cooking purposes. The oven permits of baking being accom-' plished at the same time, and the manner of articulating the intermediate plate 19 relative to the oven shell retains heat within the oven, while the central opening 20 allows the heatof the burner to reach the center plate or grid 15 and spread outwardly beneath the cooking top 15. 7

When the main legs are used as supports for the oven, said legs may be inclosed be- Eeath the oven so as to form a heating cham- What I claim is 1. A stove comprising an oven shell hav ing a doorway, a door for the doorway of said oven shell, a bottom plate set in said oven shell, corner pieces connecting said bottom plate to said oven shell and provided with auxiliary legs, an intermediate plate set on said oven shell and said corner pieces, a cooking top carried by said intermediate plate, and a burner in said oven shell.
